Nov 09, · Part 4 of 4: Using a multimeter to check IAC valve resistance specification Step 1: Gain access to the IAC valve. Consult the vehicle service manual for the location of the IAC valve on your Step 2: Disconnect IAC valve. Locate the IAC valve electrical connector and unplug the IAC valve. . In this video I show you an easy way to check an idle air control valve. In this video I show you an easy way to check an idle air control valve.
The idle control valve in your vehicle is mounted on the throttle body and controls the air flow into the engine from around the throttle body. The valve, as the name suggests, controls the idle. When this valve is dirty, your vehicle will have a hard time idling. Check to see if the valve is functioning properly how to design a pie chart in excel physically examining it.
If it's dirty, you can clean it; if it's not dirty and your vehicle is idling rough, how to use streamers fly fishing control valve may have failed. You will be able to confirm this with a voltmeter.
Open the hood and remove the screws holding the idle control valve to the throttle body on the back of the engine. Unplug the electrical plug running to the control valve.
It may pull right off, but you may need to squeeze the release tab on the top of the your plug before it will come off the end of the valve. Pull the idle control valve off the throttle body and turn it over to expose the valve openings. Touch one of the leads on the voltmeter to one of the terminals on the end vaove the valve. Go, touch the other lead of the voltmeter to the other terminal on the end of the valve. The reading should be "0. If it falls outside of this range, your valve has failed and must be replaced.
Check the inside of the valve openings for dirt if the valve passed the ohm test resistance test. The sensor will be dirty if the valve is otherwise functioning properly.
Spray the sensor liberally with electronic parts cheeck and allow the fluid to drain out of the valve openings until it runs clear. Let the sensor dry completely and then reinstall it onto the throttle body.
Installation is the reverse of removal. Start your vehicle's engine and allow it to idle for several minutes hoow that the idle control valve can relearn the air flow required for the engine.

I have written for Demand Studios since Step 1 Open the hood and remove the screws holding the idle control valve to the throttle body on the back of the engine.
Step 2 Unplug the electrical plug running to the control valve. Step 3 Pull the idle control valve off the throttle body and turn it over to expose the valve openings. Step 4 Turn the dial on the voltmeter to falve. Step 5 Touch what is a photo scanner of the leads on the voltmeter to one of the terminals on the end of the valve.
Step 6 Check the inside of the valve openings for dirt if the valve passed the ohm test resistance test. Step 7 Spray the sensor liberally with electronic parts cleaner and allow the fluid to drain out of the valve openings until it runs clear. Step 8 Let the sensor dry completely and then reinstall it onto the throttle body. Tips For specific information about checking your vehicle's idle control valve, consult the vehicle's manual see Resources.

Go behind the engine and unscrew the idle air control valve from the throttle body. 2) Pull the electrical plug off the control valve. If the top has a release tab, then squeeze that as you pull. One of the easiest ways to test your idle air control valve is to simply look at it. Check to see if the valve stems have dirt on them or if they are burnt. Check the valve opening on the throttle body to make sure that there is solid contact between the valve and the stem. Step 3 - Use Voltmeter. Turn the valve over until you see the valve openings.
The idle air control valve manages the amount of air which flows into your engine. This, in turn, allows the valve to manage the idle speed of the engine.
Of course, the engine control unit communicates with the idle air control valve. It is what tells the valve when to open or close, resulting in more or less air flowing to the engine. The engine idle speed refers to the number of RPM revolutions per minute while the vehicle is not moving.
Based on the current conditions, the RPM adjusts accordingly by letting in just the right amount of air into the engine. However, when your idle air control valve is filthy or dirty, the idling process is more difficult. That is why you need to clean your idle air control valve periodically.
The longer you wait to clean the valve, the more frequent your engine will idle rough. How will you know whether your idle air control valve is dirty or not working altogether? Well, you can use a voltmeter to determine whether the valve is working. If the test shows that it is working, then it means your valve is dirty. But if the test shows the valve is not working, then you need to replace your valve. The tools and accessories you will need to do the test include a screwdriver, voltmeter, socket wrench, electronic parts cleaner, and 10mm socket.
Go behind the engine and unscrew the idle air control valve from the throttle body. If the top has a release tab, then squeeze that as you pull. You should see the valve openings there. The normal reading is between 0. Anything outside of this means your idle air control valve is bad. You should see dirt on the sensor if the valve is functional.
Spray an electronic parts cleaner solution onto the sensor of the valve. Let the fluid drain through the openings of the valve. After that, screw the valve back onto the throttle body. Basically, start from step 3 and then go in reverse. Could I use mass air flow sensor cleaner to clean this part? The car ran fine til I replaced the abs control module and I cleaned the engine with some exterior cleaner made for cars. Facebook Pinterest Twitter.
